Leafhopper
Sap-feeding pest causing hopper burn and stippling.
Leafhoppers (Empoasca spp. and related species) feed using piercing-sucking mouthparts, causing white stippling, hopper burn, leaf cupping and reduced vigour. Adults are very mobile and nymphs run sideways when disturbed. Biological controls include Orius species, Amblyseius swirskii and Beauveria bassiana, supported by good weed control and crop hygiene.
